What is an air source heat pump?

An air source heat pump is a heating unit which is located external to the property. Highly energy efficient systems, the units transform outside air into heat and hot water – irrespective of the temperature outside.

Although powered by electricity, air source heat pumps are renewable energy sources – 75% renewable energy and 25% electricity. On average, every unit of electricity the pump uses for power, it will generate 3 to 4 units of heat.

What are the benefits of installing an air source heat pump?

  • Receive up to £1,400 cashback – per year – with the Renewable Heat Incentive. This example is based on an average 4-bedroom property with a G-rated oil boiler
  • Save up to £1,350 on your heating bills
  • Reduce your CO2 emissions and carbon footprint
  • Air source heat pumps require very little maintenance. Just an annual service is required for the manufacturers warranty to remain valid
  • Fast, no mess installations
  • No need for fuel deliveries
  • You have the ability to control your heating from your phone, with the use of smart heating controls – saving you both energy and money

What is RHI?

RHI – otherwise known as the Renewable Heat Incentive – is the scheme put in place by the Government, to financially reward customers who are benefiting from renewable energy sources to heat their properties.

There is a separate RHI for domestic and non-domestic customers. The RHI is a seven year scheme where you will receive payments every quarter.

Air source heat pump – FAQs

Believe it or not, your household refrigerator uses a similar process as an air source heat pump. Using technology to remove heat from the fridge to keep the food cold, an air source heat pump works in reverse. Heat pumps extract outside air, turns the air into heated energy and pumps it into your home.

Using the same ‘vapour compression cycle’ as your fridge to produce heat, the heat pump can take a few degrees of outside heat and upgrade it to provide all the heating and hot water you need. Running on electricity, the air source heat pump converts 1 unit of energy into 3 or 4 units of heat.

The cost of an air source heat pump installation depends on varying factors such as the size of your property, the levels of insulation and thermal efficiency, the number of radiators plus more. To find out how much it would cost to install would require a visit from our expert team. Once we have created the system design and assessed whether or not new piping or new radiators need to be fitted, installations shouldn’t take much more than a couple of days.

Installations are eligible for 7 years of cashback with the Renewable Heat Incentive, which significantly offsets the cost of install. You’ll also notice immediate savings on your energy bill. You can also be eligible for a Metering and Monitoring Package with an air source heat pump system, which provides an additional payment of £1,610.

Under the Permitted Development Regulations, air source heat pump noise levels must not exceed 42dB(A) within 1m of a neighbour’s nearest room. As our pumps are registered with the Quiet Mark, they can be located closer to your neighbour’s property and pass any planning, if required.

Some of the latest models offer superb style, market-leading energy efficiency and sound levels and are 3 times quieter than previous models, virtually eliminating planning restrictions.

Should you have a very large property that requires more than one heat pump, planning will be required.

The UK can be a cold place – especially in winter. Air source heat pump systems will continue to work at outdoor temperatures as low as -20c. Sometimes more depending on the manufacturer. This means your home will continue to be warm, even if there is snow on the ground.

Although the fan on the pump will continue to turn and make a slight whirring sound, they are not all that noisy. The air source heat pumps we supply and install are registered with the Quiet Mark.

As regular boilers can be linked to smart controls, so can air source heat pumps. The systems are built with smart controls to enable you to monitor your heating and make changes to settings wherever you are.
